COMBINATION-TOOL FOR BRICKLAYING.

Specification of Letters Patent.

Patented Sept. 18, 1906.

Application filed June 19,1905. Serial No. 266,055.

To ail whom, it may concern:

Be it known that I, SYDNEY Ronnn'rs, a citizen of Great Britain, residing at 13 Lodge road, Rugby, in the county of Tarwick, England, have invented a new and useful Combi nation-Tool for Bricklaying and I do hereby declare the following to be a full, clear, and exact description.

My invention as an improved article of manufacture relates to combination-tools es pecially adapted for bricklayers use; and the object of my invention is to provide an instrument which by the assemblage of a number of different features heretofore employed individually as separate tools will enable the operator to prosecute his work more accurately and speedily by means of all of these features being incorporated into one combination-tool.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which- Figure 1 shows a bottom plan, side, and end view of the base-plate forming part of my invention. Fig. 2 shows a plan view of an adjustable miter-bevel blade. Fig. 3 illustrates a plan view of these combined fea tures. Fig. 4 shows a front, side, and plan view of a clasp used in connection with the article illustrated in Fig. 1. Fig. 5 illustrates the side and plan view of a thumbscrew forming part of the article shown in Figs. 1 and 3. Fig. 6 is a side view; Fig. 7, a plan view of a section of a building-wall under construction, showing the application and use of my improved combination-tool as a bricklayers line stretcher and holder; and Fig. 8 is an elevation of a corner of a wall, illustrating the use of my invention as a lumb-line.

In the drawings, as shown in Fig. 1, the base-plate A consists of a flat metal plate with a handle extension on one end thereof, while the other end is square and has two dovetailed recesses h centrally located thereon. The upper side of this base-plate A has a central longitudinally-extending groove, as indicated in Fig. 1 in dotted lines, for the re ception of the bricklayer s lines, which can be fastened to a kerf in the handle, said kerf forming a continuation of the countersunk groove. The bottom side of the base-plate 1s stepped at e and f at regular intervals and h projecting beyond the finished form gages for marking threeuarter bricks. A tapped hole 9 in the base-p ate A receives the set-screw D (illus trated in 5) or the clasp C, as shown in Fig. 4. A bevel-blade B with a central slot and end miter, asshown in Figs. 2 and 3, can be placed on the base-plate A and is fastened downby the set-screwD. Said blade can also be deflected to correspond with the line of different angles as permanently marked on the baseplate A, or this blade can be individually used as a foot-rule, having marked thereon on one or both edges inch measurements and their subdivisions.

In the use of my improved combinationtool, and if employed as a socalled tingle for the purpose of taking up the sag in a long range of line the base-plate A is placed face down on a brick with the dovetailed recesses part of the wall, and the tool then being of the same height as the next course of bricks to be laid from the two end corners toward the middle, as shown in Figs. 6 and 7, the line is twisted through the recesses h, and the line being now tautened from both ends the usual vertical sag is effectively taken up.

In order. to use this instrument for holding the ends of the bricklayers line, the clasp C is inserted in the tapped hole 9 of the baseplate A and projects therefrom at right angles, as shown in Figs. 6 and 7. If either one of such plates is held against the edge of the building and the line is passed through a kerf quarter, one-half, and

in the handle of the base-plate, pulled taut,

and secured by twisting the line over the handles, then these two instruments will hold themselves in position by frictional resistance, the clasp C bearing against the parallel ends of the wall and the base-plate A bearing against the front side of the wall under construction.

It is obvious that the mitered bevel-blade B can be set to correspond to any of the angles marked on the base-plate A if it is desired to employ this tool for the purpose of marking angles on the plane surface for radial an les, &o.

The base-plate A, used as a plumb-line, as illustrated in Fig. 8, is readily constructed by passing a plumb-bob line through the sawkerf in thehandle. The small space left between the two dovetailed recesses h on the baselate a indicates to the play of the plum -line the exact vertical position to be obtained in the usual manner.

IIO

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A combination bricklay'ers tool, consisting of a base-plate A having gages e and f, notches h commonly known as a tingle and provided with groove and slot and having angles marked thereon, substantially as shown and described.

2. As an improved article or manufacture, a combination bricklayers tool consisting of a base-plate having stepped gages for marking off thereby subdivisions of the lengths of bricks, a tingle to prevent sag in long lengths of line, a groove and slot for guiding and fas tening the bricklayers line, angles marked thereon and an adjustable miter-blade pro vided with linear measurements adapted to operate in conjunction with lines indicating the angles marked on the base-plate afore mentioned, substantially as shown and described. v

3. A combination bricklayers tool, con sisting of a base-plate having stepped gages,

a tingle on one end thereof, and a centrally v located groove longitudinally extending over the surface of the base-plate, a kerf in the handle of the base-plate, said kerf being a continuation of the groove, substantially as shown and described.

4. A combination bricklayers tool, con sisting of a base-plate provided withstepped gages, a tingle, a centrally-located groove V base-plate provided with a tingle at one endther'eof, a centrally-located groove entering in the saw-kerf in the handle of the baseplate, a tapped hole and a screw-threaded clasp inserted in said tapped hole at right angles to the base-plate, said clasp being provided with a centrally-located kerf for I sertion of a bricklayers line, substantially as l shown and described.

In testimony whereof I have slgned my name to this specification in the presence of two witnesses.

SYDNEY ROBERTS.
